Estimate adult body mass index from weight and height. Choose one unit mode: metric (kilograms and centimeters) or US (pounds, feet, and inches). Modes do not mix. BMI is weight in kilograms divided by height in meters squared. The page shows BMI rounded half-up to one decimal and a general WHO-style category from the exact BMI. This is not a diagnosis and not medical advice.

A person who weighs 70 kilograms and is 175 centimeters tall. Height in meters is 175 ÷ 100 = 1.75. BMI is 70 ÷ (1.75 × 1.75) = 70 ÷ 3.0625 = 22.857142857…, which displays as 22.9. The exact value is in the Healthy weight range (18.5 to less than 25). This is not a diagnosis and not medical advice.
BMI = weight_kg / (height_m ** 2). Metric: height_m = cm / 100. US: kg = lb × 0.45359237; total_inches = feet×12 + inches (inches 0–11); height_m = total_inches × 0.0254. Display = round1(exact BMI), half-up to 1 decimal. Category from the exact BMI. round1 uses the same half-up spirit as round2 elsewhere (scale by 10, Number.EPSILON, Math.round).
Estimates are for planning materials only. Check the paint label for actual coverage and buy enough for touch-ups.
Metric mode uses kilograms for weight and centimeters for height. US mode uses pounds for weight and feet plus inches for height. One mode at a time — do not mix. Inches must be from 0 to 11; put larger values into feet instead (for example 6 ft 0 in, not 5 ft 12 in). A missing mode, or a weight or height that is 0, negative, blank, or not a number, is rejected.
BMI = weight in kilograms ÷ (height in meters × height in meters). The page converts your inputs into exact kilograms and meters first, then divides. The result is rounded half-up to one decimal for display only. A rounded height or weight is never fed back into the formula.
The labels follow general WHO-style adult ranges applied to the exact BMI: under 18.5 Underweight; 18.5 to less than 25 Healthy weight; 25 to less than 30 Overweight; 30 and above Obese. The category uses the exact BMI, not the rounded tenth. For example, an exact 24.96 that displays as 25.0 is still Healthy weight.
No. This is not a diagnosis and not medical advice. BMI is only a general adult body-mass index estimate from weight and height. It does not measure body fat, ideal weight, calories, age, or sex. Talk to a qualified clinician about your health.
Pounds convert with × 0.45359237, so 150 lb is exactly 68.0388555 kg. Height is 5×12 + 9 = 69 inches, times 0.0254 = 1.7526 m. BMI is 68.0388555 ÷ (1.7526²) ≈ 22.15090042971516, which rounds half-up to one decimal as 22.2. The category is Healthy weight.
